\fB/usr/lib/security/$ISA/crypt_bsdbf.so\fR
.fi

.SH DESCRIPTION
.sp
.LP
The \fBcrypt_bsdbf\fR module is a one-way password hashing module for use with \fBcrypt\fR(3C) that uses the Blowfish cryptographic algorithm. The algorithm identifier for \fBcrypt.conf\fR(4) and \fBpolicy.conf\fR(4) is \fB2a\fR.
